While the OCaml way looks better, the Nim version allows for multiple types to have the same values, without repetition. It also has the advantage that multiple variants can concisely be matched upon using sets like `{opSub, opMul}` While the OCaml way looks better, the Nim version allows for multiple types to have the same values without repetition. It also has the advantage that multiple variants can concisely be matched upon using sets, eg `node.kind in {opSub, opMul}`.
